Installation
BEFORE INSTALLATION, PLEASE REFER TO THE SAFETY WARNINGS,
APPROVALS REQUIREMENTS, AND EMC REQUIREMENTS IN APPENDIX A,B
AND C.
Supply Voltage & Connection
AC
100 - 240V AC without adjustment.
Optional DC
48V DC without adjustment.
The Sprint 2 may be optionally DC or AC powered. The AC power supply is a switched
mode unit, whereas the optional DC power supply unit is a DC to DC convertor. Both allow
considerable input voltage variation.
Environmental Considerations
The Sprint 2 Multiplexer must be operated under the following atmospheric conditions:
Temperature: 0 to 40 degrees centigrade.
Humidity:
0% to 90% non-condensing.
Air Pressure: 86 to 106 kPa.
Mechanical Construction
The Sprint 2 is housed in a 2U tall 19" enclosure. An optional rack mount kit is available on
request. Eleven LEDs on the front panel indicate the current status of the multiplexer.
The multiplexer MUST be disconnected from the power supply before opening the unit
or changing any network connections.
Screws on the left, right and top of the enclosure are removed using a Posidrive screwdriver
to access the interior. This allows installation of interface and option cards. Please read the
relevant option manual before attempting any retrofit operation.
The rear panel illustrated in Appendix D accommodates the link interface connectors and
supervisor port.
